I am a male and I frequently have a problem when masturbating. I find that along with getting that great orgasmic sensation I also have an uncomfortable feeling, it feels sort of like I need to urinate even though I don't really need to urinate, it also feels sore and just overall horrible and I don't mean my penis is sore I mean I feel sore on the inside. sometimes it's only miner but other times it can be so bad that it totally ruins the sexual pleasure.

Do any of you other men out there ever get this problem and know how to stop it if that's possible?
